tengine
特性:
继承Nginx-1.8.1的所有特性，兼容Nginx的配置；
动态模块加载（DSO）支持。加入一个模块不再需要重新编译整个Tengine；
支持HTTP/2协议，HTTP/2模块替代SPDY模块；
流式上传到HTTP后端服务器或FastCGI服务器，大量减少机器的I/O压力；
更加强大的负载均衡能力，包括一致性hash模块、会话保持模块，还可以对后端的服务器进行主动健康检查，根据服务器状态自动上线下线，以及动态解析upstream中出现的域名；
输入过滤器机制支持。通过使用这种机制Web应用防火墙的编写更为方便；
支持设置proxy、memcached、fastcgi、scgi、uwsgi在后端失败时的重试次数
动态脚本语言Lua支持。扩展功能非常高效简单；
支持按指定关键字(域名，url等)收集Tengine运行状态；
组合多个CSS、JavaScript文件的访问请求变成一个请求；
自动去除空白字符和注释从而减小页面的体积
自动根据CPU数目设置进程个数和绑定CPU亲缘性；
监控系统的负载和资源占用从而对系统进行保护；
显示对运维人员更友好的出错信息，便于定位出错机器；
更强大的防攻击（访问速度限制）模块；
更方便的命令行参数，如列出编译的模块列表、支持的指令等；
可以根据访问文件类型设置过期时间；
tengine安装：
tengine-2.1.2.tar.gz
安装所需的扩展模块：
yum -y install zlib-devel pcre-devel openssl-devel
yum groupinstall "development Tools" "Server Platform Development" -y
tar xf tengine-2.1.2.tar.gz -C /usr/src/
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_gzip_static_module --with-http_stub_status_module --with-http_ssl_module
make
make install
